【摘要】 分析中国、东南亚和南亚的 96份普野的 12个等位酶位点 ,及 885份地方品种的 10个酶位点的遗传多样性。结果表明 ,中国与南亚普野和栽培稻在Est 2、Est 10、Mal 1、Cat 1四个位点发生了地理分化。中国普野以Acp 12 、Acp 2 0 、Amp 2 2 、Est 2 0 、Cat 12 、Mal 11基因型为主 ,是偏粳型。南亚普野以Acp 12 、Acp 2 0 、Amp 2 2 、Est 2 1/Est 2 0 、Cat 11、Mal 12 基因型为主 ,是偏籼型。中国和南亚是两个独立的稻作起源中心。更多还原

【Abstract】 accessions of common wild rice at 12 isozyme gene loci and 885 varieties of cultivated at 10 isozyme loci, which were collected from china, Southeast and South Asia were analyzed. The results demostrated that the geoghraphic differentiation took place in common wild rice and cultivated rice between China and south Asia at Est-2、Est-10、Mal-1 and Cat-1 loci. The main genotype of Chinese common wild rice is Acp-1 2、Acp-2 0、Amp-2、Est-2 0、Cat-1 2、Mal-1 1 which is Japonica-like type. The main genotype of South Asian common wild rice is Acp-1 2、Acp-2 0、Amp-2 2、Est-2 1/Est-2 0、Cat-1 1、Mal-1 2 which is Indica-like type. It was hypothesized that China and South Asia are two independent centers of origin for Asian cultivated rice.更多还原
